Our nightly build process was broken for a long time, such that it generated PDB files that were a few hours different in age than the corresponding image files. I have s
Or you could just use the suggestion here to have windbg ignore mismatched signatures and age:

... While by default it [windbg] also does not allow to load unmatched debug information, .symopt debugger command can change the default behaviour. After we have issued “.symopt+0x40” command, the debugger will happily accept and load unmatched PDB and DBG files.
Hope this helps.
